The Rice Alliance for Technology and Entrepreneurship has announced the 17 companies joining its second accelerator — and the program didn't have to venture very far for some of them.

The Rice Alliance Clean Energy Accelerator named the early- to mid-stage startups that will participate in its second annual class — five of which are based in Houston:

  • CLS Wind is developing a unique system to lift any size wind turbine component to any height using smaller-capacity cranes, an efficient, safe and economical solution to a lack of available high-capacity cranes and vessels.
  • Dsider is developing a low code solution for climate minded organizations to visualize and analyze their carbon pathways to plan, prioritize and operate sustainably and economically.
  • Emission Critical is developing carbon accounting and management software as a service to help enterprises solve end-to-end carbon footprinting with minimum effort
  • NanoTech is developing advanced materials to help businesses and individuals solve fireproofing and thermal insulation challenges with new world particles.
  • Pressure Corp is developing waste pressure power systems to help midstream gas companies solve how they reduce emissions by providing the technology, capital and expertise required to achieve their environmental, social and governance goals.

The 10-week program kicks off at the university’s Rice Alliance Energy Tech Venture Forum in September, and concludes on Demo Day on Nov. 17. While mostly virtual, the program will welcome the complete cohort to Houston three times throughout the accelerator.

The full cohort of companies — which come from seven states and four countries — has already collectively raised more than $54.5 million. Over the 10 weeks, the companies will receive support and mentorship to help them raise funding, launch pilots, win adoption into the marketplace, and more.

The 2022 cohort specializes across the spectrum of clean energy, including advanced materials, digital technology for energy, energy efficiency, energy storage, geothermal energy, hydrogen, waste heat to power, wave energy, and wind energy. The rest of the cohort includes:

  • Atargis Energy, based in Colorado, is developing an innovative twin hydrofoil-based wave energy converter technology combined with a proprietary feedback control system that combines real-time sensors, predictive algorithms and machine learning to make possible the first predictable, low-cost, utility-scale baseload electricity sourced from ocean waves for utilities and other electricity providers.
  • Based in Somerville, Massachusetts, Eden GeoPower Inc. is developing electrical reservoir stimulation technology to help geothermal, petroleum and mineral resource developers solve issues with low-permeability reservoirs by effectively increasing permeability in a way that uses less water and emits less CO2 than traditional stimulation methods.
  • FuelX has developed solid-state hydrogen power systems to help transportation manufacturers meet their customers’ growing performance requirements by using high-energy-density systems that outperform batteries and other pure hydrogen solutions. When coupled with a green hydrogen raw material, FuelX systems provide zero-carbon power.
  • GeoGen Technologies — a Canadian company — is developing a new kind of geothermal that allows oil and gas companies to convert end of life oil and gas wells to economic geothermal.
  • Durham, North Carolina-based GOLeafe uses organic materials and non-energy or capital-intensive equipment toproduce graphene oxide — the world's strongest, thinnest and most conductive material — through a process that’s 10 times more cost efficient and eco-friendly using readily available materials such as hay, sugar and wood chips.
  • LiNa Energy is commercializing safe, sustainable, solid-state sodium batteries that contain no lithium or cobalt.
  • Luminescent, based in the United Kingdom, is building an isothermal expansion heat engine for waste heat recovery along gas transmission pipelines.
  • Nobel improves fuel efficiency for gas-fired power plants with drop in, reliable supersonic combustion technology.
  • Quino Energy — based in California — produces low-cost, long-lifetime aqueous organic flow batteries for grid storage applications. The charge is stored in specially designed organic molecules called quinones, which are produced from cheap chemical precursors in a proprietary, zero-waste process.
  • Viridly, based in Texas,is developing geothermal power plants with patent-pending generator technology alongside geothermal greenhouses to provide the first financially viable way to confidently deliver and scale up the development of baseload geothermal electricity.
  • Another Canadian company, Volta Technique’s compressed air storage and management technology addresses the unpredictable and ever-increasing cost of energy for large commercial and industrial electricity users while enabling decarbonization of the electricity grid through higher integration of renewable energy.
  • Wootz, another Texas company, is developing a scalable manufacturing process to produce sustainable, cost-effective, high-performance carbon nanotube materials at commercial scale to replace or enhance traditional metallic conductors.

Twelve companies participated in Class 1 of the Rice Alliance Clean Energy, which was delivered virtually last summer. The 12 startups in that inaugural class have raised a combined $6.5 million in funding, identified and launched pilots, met investors, hired staff and moved their offices to Houston.

The program is supported by founding sponsor Wells Fargo and supporters: BP, Baker Botts, Chevron, ExxonMobil, Halliburton Labs, Equinor, Microsoft, NRG, Saudi Aramco Energy Ventures, Shell Ventures, Sunnova, TotalEnergies, Tudor Pickering Holt, Canadian Consulate, TC Energy, Phillips 66, and ENI Next.

Houston innovator: The future of decarbonization is data-driven decision making

houston innovators podcast episode 123

Decarbonizing the energy industry would be a lot more successful if companies had the tools to more efficiently and accurately track their carbon footprint.

Sujatha Kumar has created that tool with her startup Dsider, a decision intelligence platform with a suite of software tools to equip energy businesses with the data they need to make informed decisions. Kumar, founder and CEO, has spent years consulting companies on finding operational success and now is using her Dsider platform to streamline results.

"When I looked at how companies made decisions — especially in the decarbonization world — I realized there was a big gap to be filled, and that's how Dsider was born," Kumar says on the Houston Innovators Podcast.

"We are creating transparency so that companies can have a digital footprint of how decarbonization can happen, and allowing them to make decisions along the way that are always going to be towards decarbonation and not forgetting that everything has an economic trade off," she continues.

Dsider, a Greentown Houston member company, is targeting the energy industry specifically — oil and gas, petrochemicals, utilities, etc. She says Dsider has the potential to bring decarbonization decision making to other industries as well. For now, Dsider has a few customers and is actively seeking out a few more.

"One of the first few things we want to do is get traction with a handful of customers," "We have the rigor and we are able to make sure the products we have brought to market are really something that is going to land well with customers. From that, we want to see the growth accelerator."

This year, Kumar hopes raise seed funding and grow her team and customer base. She still is working with companies as a consultant with her business, Ayatis LLC. She says the two roles go hand in hand — Dsider is a tool she can offer her consultancy clients.

"We live in that world today where a single role isn't enough for us," Kumar says. "The consulting angle has really helped me think through the customer journey. ... That has really created the Dsider and product journey. In order for me to grow Dsider, I can't balance the consulting that I used to do, so all of my consulting will be geared towards helping customers decarbonize and leveraging Dsider to do that."

Kumar shares more on Dsider's potential impact on decarbonization and how she has observed changes in Houston's innovation ecosystem on the podcast. Listen to the full interview below — or wherever you stream your podcasts — and subscribe for weekly episodes.

Intuitive Machines engineer talks STEM, innovation, and second chances

Innovator Interview

Mario Romero is an assembly, integration, and test engineer at the innovative Houston aerospace company Intuitive Machines. He previously served as a Navy SEAL and an EVA Flight Simulator Specialist at NASA.

Intuitive Machines landed its IM-2 mission on the moon last month, before calling an early end of mission. The company reported that its lunar lander was on its side, preventing it from completing the mission as planned.

Still, the IM-2 mission landed closer to the lunar South Pole than any previous lander, according to NASA. And the company still has plenty of innovative projects in the works.

The company secured about $2.5 million from NASA to study challenges related to carrying cargo on the company’s lunar lander and hauling cargo on the moon. The lander will be used for NASA’s Artemis missions to the moon and eventually to Mars.

“Someone has to do it; in fact, the more the merrier,” Romero says on being part of an innovative culture.

“Competition forces innovation, and if I can be selfish for a moment, I think it’s of particular importance for Intuitive Machines because my extremely capable team is more than worthy of having their place stamped in history. We, as a species, have to strive to become a multiplanetary species. Incidentally, part of the trickle-down effect of innovation often leads to spin-off technology that in some way benefits humanity here on Earth.”

Last year, Romero was awarded the key to the city from his hometown of Vineland, New Jersey, and made it a point in his speech to give kids a chance to succeed in the future.

“I am the product of many chances, secondary, tertiary, and more, given to me,” Romero says. “Many of these were admittedly entirely undeserving. I look back now and recognize that those teachers, judges, police, etc. might have all seen something in me that I couldn’t then see in myself. … This is precisely why I often emphasize giving kids multiple chances. Kids are kids, and you can never fully know how you’re inspiring them in the moment, nor how the chances that you give them will affect the trajectory of their lives.”

Texas is expected to represent nearly 10 percent of future STEM opportunities in the nation, and nine of the 20 biggest employers in Texas are STEM-related.

As STEM has become increasingly popular in high schools and at the university level, and the aerospace industry continues to innovate, it is possible that many young future innovators may take the same path a young Romero did.

“I think it’s natural that when new leaps are made in the STEM fields, and in the aerospace realm at large, the youth in general become galvanized by it,” Romero says.

“It’s exciting and reinvigorating to understand that humanity is on the cusp of the next great adventure. As fantastic and essential as this is, I want to emphasize the importance of the arts as well. It has an important place and an important role to play in our evolution, so I personally don’t limit youthful interest to STEM alone. There are fantastic works of art awaiting us, in all their variety, that will come as a result of the efforts and innovation.”
